Thirty years ago the bespectacled scientist burst onto the UFO scene by exposing the US government as having spaceships from another world hidden in Nevada. At least that was the gambit.

This new motion picture of Bob Lazar has a title that is interestingly punctuated: no commas required. When the title’s style is of interest, the rest of the movie may not be. Bob Lazar: Area 51 & Flying Saucers.

After a whirlwind of dangerous controversy, Bob Lazar disappeared into the mists of the 1980s like a rock video from MTV. Like Edward Snowden, he was unverifiable, having claimed his identity was erased by the government’s black ops. He feared he would be erased.

So, he went underground and refused to have anything to do with George Knapp and the UFO radio network that later evolved into Ancient Aliens and a cottage industry of crypto-science.

Now he returns like a bad penny in a new documentary.

He looks fairly much the same as ever: characteristic eyeglasses now over a weather-beaten face. He has not gained a pound in 30 years, which may be due to alien technology.

The big questions remain: who is he? What motivated him? And why has he returned? This 90-minute film recaps much of the past but reveals not much of the present.

He seems prosperous, running some kind of science lab in Middle America. He has not gone into Witness Protection and is not living in abject fear. MJ-12 has not assassinated him. However, he is almost immediately raided by the FBI upon re-emergence. Somebody is watching.

Having successfully hidden for 30 years, we wonder why he would throw himself back into the breach. There is no answer, except the profits of the movie producers. He really has nothing more to offer, other than to provide a final chapter to the circus of his earlier life.

This is a slick, but ultimately empty documentary that covers old ground with a fresh, new coat of paint on un-Groomed Lake.
